At a specific area of a chromosome, the sequence of nucleotides below is present where the chain opens to form a replication for
olya-2409 [2.1K]

Answer: D

Explanation:

3' C C T A G G C (T) G C A A T C C 5'

The primer RNA will be 5' A C G U U A G G 3'

Polymerization of the new stand is taking place from 5' to 3' direction. This means the the template strand is read from 3' to 5' direction.

In DNA synthesis chargaff base pairing rule is always maintain. If ''A'' is present on the template strand ''T''enters in that place on the newly synthesized DNA .

RNA primase synthesizes this short primer. RNA primer contains RNA nucleotides this means If ''A'' is on the template strand, the RNA primer will be ''U''

xxTIMURxx [149]

made of three layers

has a terry layer

has a solid outer layer

Explanation:

The mantle is mechanically made up of three layers.

The rigid part that joins with the lithosphere, asthenosphere and the inner mesosphere. The asthenosphere molten, weak and relatively flows. Part of the mantle in conjunction with the crust makes up a lithospheric plate on the earth crust.

The lower layer is the is the mesosphere or middle layer. It is a solid rigid ball that is highly dense. Below this layer is the outer core.

  • The mantle is made up of ferro-magnesian minerals.
  • Density and pressure here increases with depth in the mantle
